Kraft Foods has recalled nearly 300,000 packages of its white chocolate baking squares amid fears of salmonella.

The six-ounce packages of Baker's Premium White Chocolate Baking Squares were ordered pulled from supermarket shelves, including area Albertsons, after the U.S. Food and Drug Administration detected the presence of the bacteria in some packages of the product, according to the company.

Affected packages were sold nationwide with a UPC code of 0043000252200. They contain four "best when used by" dates: March 31, April 1, April 2 and April 3. Consumers should discard any packages that meet these requirements, the company said.

Salmonella is a bacterium that causes fever, diarrhea and abdominal cramps. For people with underlying health issues or already weakened immune systems, it can cause life-threatening infections.

In a news release issued late Wednesday, Kraft said it was "aggressively investigating" the source of the problem.

Albertsons customers who believe they have the recalled baking squares should return it for an exchange or a full refund.

Consumers can also contact Kraft at 1-800-310-3704 with questions or for reimbursement.
